There are still existent phonograph recordings which provide us with rare examples of spoken speech from the late 19th century and early 20th century. The aim of this research project was to gather spoken Osaka dialect materials stored in various places and analyze them to clarify the state of spoken Osaka dialect in that period. Furthermore, by comparing this data with data on the dynamics of current speech in the Kansai region which is being collected in field studies, we are attempting to obtain an overall understanding of the nature of changes in spoken Osaka dialect.This academic year, we were able to produce a collection of transcriptions of 78 rpm recordings of Osaka "rakugo" stories, as well as a report on our glottogram survey fieldwork.本年度は、成果の報告書として、大阪落語SPレコ-ドを聴取し分析した録音文字化資料集(『20世紀初頭大阪口語の実態ー落語SPレコ-ドを資料としてー』)を作成した。また、滋賀県彦根市から岐阜県岐阜市にかけて実施した各年層男女を対象としたフィ-ルドワ-クの結果をまとめたグロットグラム集(『彦根一岐阜間グロットグラム調査報告書』)を作成した。
